AI LBERT H. BATES, OE CLEVELAND, OHIO, ASSIGNOR TO THE AMERICAN MULTIGRAFE CUMEANY, OF CLEVELAND, OHIO, A CORPORATION OF OHIO.'

DUPLICATING-MACHINE.

a To all whom it may concern;

Be it known that I, ALBERT H. Buns, a citizen of the United States, residing at Cleveland, in the county of Guyzihoga and State of Ohio, have invented a certain new and useful Improvement in Duplicating- .Machines, of which the following is a full, cleanend exact description, reference being lied. to the accompanying drawings. The object of this invention is to provide a z simpleand etlici'ent rotary printing press adapted fontlierapid production of circular letters in imitationof typewriting, wherein the body of'the letter isprinted through an inlring ribbon, and the letter-head or the signature, or both, are printed. by direct inking. 3

.e'inotl'i'er object is to provide such a ma,- chine in a form wherein all the printing surfaces are easily removable and'c iangeablex- Another object is to enable the printing atone rotation of two successive sheets, with the letter-head andbody-on one sheet and the body and signature on the other sheet,

both sheets being printed by the same face of J theiribbon. I 7

Still another object. is to proviso independent and diiierent inking forthe letter head and signature.

The invention is particularly adapted for I a rotary printing); machine oi thetype shown in application No. 432,777 filed May fi l, 1908, by Harry (1'. Gammeter, wherein the type are carried on a removable segmental member mounted in a skeleton-drum, and

i such type form is inked by a ribbon extending-across it and having its ends on spools, which are mounted in the slreleton drum opposite the type form; In my invention, 1

0 may take such printing machine and equip it with means for carrying a suitable electrotype', or other printing snrface, of either the letter-head or the signature, or both, and I. mount such member, or each of such mom- 5 hers, on the drum between one edge of the segment ct'or. the body 01% the letter and the adjacent ribbon spool. The ribbon thus passes beneath myholder for the letter-head or sisznatnre and passes outwardly between 60' it and the removable form which carries the body of the letter; and if two of my holders ere employed the ribbon passes from the other edge of the body form to theotherspoolbeneatli the second holder. filliteble Specification oi" Letters Fetent.

head or signature, or both,,is combined with v a removable member for carryingthe ty e form, so that the body of the letter may e changed, as desired. I

I am familiar with application No. 409,434; filed January 6, 1.908 by Henry C. Osborn, wherein there is shown a segmental type-carrying member about. which passes an inking ribbon combined with a printing segment Which is directly inked, and I do,

not intend. to claim herein any combination or structure which is claimed or could be claimed in Mr. Osborns-application. In.

that application, however, the relative arrangement or" the printing surfaces and the spools which carry the'ends of the ribbon therc r is difierent from that shdwn and claimed herein, and-the relation ofthe di rectly inked segment to the ribbon is difirout; the construction of my segments and the arrangements for deflecting the ribboli are different; my method of printing the signature is different; and the adaptation of direct printing to a removable semi-cylindrical type-carrying drum printing through at ribbon is mine. Moreover, in Mr, iOsborns application when two sheets are print-. ed by a single rotation of the drum they are means are provided for directly inking my Patented May 30,1911.

printed through opposite sides of the ribs bon. While this is advantageous in causing more service to be obtained from the ribboini in my mechanism both sheets printed through the same face of theribbon, thereby insuring a more absolute uniformit of produot wherethe ribbon has already een erner: oneside, or for any other reason has one side different from the other.

In the drawings, Figure 1 is a vertical cross section through t rotary printing ma chine embodying my invention; F1g.2 1's a front elevation thereof; Fig. 3 1s a I;';f.(llfil signed to carry the letter-head form; and Fig. 4 is a longitudinal sect-ion through the '10s section through the removable member de- Beneath the drum is a rotary drum. These sections are taken onthe lines iir idicated respectively by 3-3 and Hof 1g. 1-. Referring first to the general construction of the embodiment shown, 1Q represents the frame of the printing machine having abase and suitable end plates. In these end plates is journaled a shaft 11, on which are mount, .ed spiders or rings 12 and 13. These rings are braced by shouldered tie rods 18 which have nuts on their ends. The shaft, rings and tie rods constitute a skeleton drum., This drum is adapted to be rotated by a suitable crank 14 or in other suitable manner. impression p1aten 15 which-has a gear 16 meshing with ed to be occupied t type-holding segment rests near ment is held on the drum by the gear 17 'onthe drum ring 13. I a 20' represents the body of the removable printing member-which is shown as a semicylindrlcal piece of metal, reinforced; by the transverse webs 21. Into the surface of this member are set longitudinal rails 24 'provid-f ing between them under-cut grooves ada t- :by grooved Qzpe; T is ts ends on the periphery of the ring 12 andifla suitable are shaped projection, 19 on the ring 13.. The stiffening webs rest at'their edges substantially against the tie rods 18, the web's. being grooved for that purpose. The sega pair of dogs 30 which surround the shaft 11' and have turned over ends extending through openings in the webs, these dogs being held in place by set screws 33. Loosening of the set screws 33 allows the shifting of the dogs to release the segment so that-it may be entirely removed and another similar segment form used, or

'stantially after the manner --them toward the their holding 'and driving 7 thus entirely independent'ofi substituted for it. The segment is long enough arcually to carry the longest page longer, as hereinafter explained. p

The type on the segment are inked by a ribbon carried by the druni itself. For this purpose there are provided suitable rib-1 bon spools 40 mounted between the end members 12 and 13 of the skeleton dr'umj. v These spools'en'gage at their'ends' with ratchets. 41 by WhlCll they may be' fed by suitable mechanism, carried by theend member 13. For this purpose, I have shown a pawl46 on a strap .45 which surrounds and is driven by a stationary eccentric a7. This pawl ;is double shouldered and adapted to en age either ratchet, and the am made is hel by suitable detents,-not' own," This is sub- "f the m nism shownin Mr. Gam'metersap' N0.240,167.' The spools are show ins plape by a suitablefisprin' echa 4 se ds"- e hai a he type 11 1 1 ingsegment. t The paper may be fedto the printing second removable segment 8 continually rotated, and the, latter of which is carried by arms 52, one of these arms having aroller which cooperates with the cam 53 on the rin 13, whereby as the drum is rotated, the r0 er 51 is raised or lowered to control the paper feed. This paper feeding mechanism 1s substantially the sameas that shown in Patent No. 846,992.

The vconstruction above described is shown in the application of Mr. Gammeter No. 432,777, refered to. "In my invention, I mount on the, rings 12 and 13 a suitable segmgntal member which lies outside of the m face 71 which may be an electrotype or other bon and carries a suitable printing sur member for printing the letter-head. As 7 over stifl', preventing itsvsagging at its centra ortion. Near its ends, the arc-shaped portlon of the segment extends over the," rings 12 and 13as shown at 7% and is se cured in place by'suitable screws 79 passing through such flanges'into the rings; ,The proper position 0 the segment longitudinally is insured by annular bosses on the outer sides of the endmost webs 77 which abut'the rings;12 and 13.

The above construction makes a very easily removable member and at the same time one which will be accurately fitted in place. Different electrotypes or other-printing surfaces may be secured to the member as desired, or diflerent segmental members may be substituted. v

scenes of the removable type carrying member so as to bring the signature close to the last Where the ribbon draws across the end of thetype-carrying segment, a roller may be employed, as shown at 85, tosreduce the friction, or the edge of the segment may be simply "rounded, as shown at 80. Where the.

roller is employed, it may he carried by the segmel it, or by the rlngs 12and 18, as desired. Fig. 1 shows the roller 85 as having gudgeons extending into the rings 12 and 13,

inkin a well known manner, tliis roller be ing mounted in arms 91 which are rigid on a rock shaft 98 journaled in the frame standards, the roller being drawn toward the drum by springs 92. On the shaft of the inking roller, or otherwise operating to rock the shaft 93, is a roll 9st which lies lover and cooperates with a cam 95 on the drum. W'hen the ribbon'printing portionof the drumis passing the inking roller 00, a portion of the cam of larger radius is acting on the roll 94,.holdingthe roller 90 out of action. Before the electrotype comes opposite theroller 90, however, the depressed portion of the cam allows the springs 92 to draw the roller inwardly toink the electrotype. The inking of the signature surface might lfn order that it may be inked by ink of a different color, however, i provide the roller 100 mounted between rook arm's 101 on a rock shaft 103. This rock shaft has a-roclc arm 10th which extends in the opposite direction and is connected with a loose arm 105 through an'interposed compressible spring the cam 95, such outward projection. extending farther than the main enlarged portion of the cam. The result of this is that when either the reduced portion of the/cam, or the portion of intermediate radius is passing the roller 107, the same is not forced outwardly enough to cause the inking roller to engage any ofthe forms, When, however, the surface 109 comes into engagement with the roll 107, the inking roller engages the signature form under a spring pressure. extra projection 109 passes the roller of the other inking roller, it simply moves the same outwardl idly. I A light tension spring-108 (Fig. 2) holds the roller 100 normally in idle position.

' From the above described construction, it will be seen that each of my segmental direct When this printing members may be mounted on the drum whenever desired or removed therefrom without varying the operation of the portion of the machine which prints through the ribbon. The segment which carries the letter-head may be used alone, or that which carries the signature alone, or either orhoth used with the ribbon printing portion. The

drum may be constructed of such size that the segmental member 20 will just ca rry the body of an ordinary letter, allowing both my letterhead and signature printer to be used at the same time so that one rotation will print the letterhead, the body of the letter and the signature. 1

To make the machine more adaptable. however, the type carrying segment 20 may have a large enough surface to carry type for the lo est sheet of paper in common use, that is, legal size. which commonly thirteen inches in lengtln The bodyportion" of a circular letter is seldom over six or seven inches on the first sheet and somewhat longer on the second sheet, so that by making the diameter of the drum approximately ten inches, and thus providinga seini' cylindrical typecarr'ying surface of about fifteen inches the surface maycarry the body portion of two successive sheets. .ziccordingly, such a. machine can print one sheet with the letter-head and the second sheet with the signature,-the form of thefirst and second sheets being so mounted on the drum that. the

first sheet begins substantially at the edge of theseginent nearest. the letter-head electrosheets of a letter areprinted through the.

same ribbon so that they are identical in appearance. r

4 here two sheets are printed by one rotation of the drum, it is desirable to have the paper feed interrupted so as to insure the properstarting of the second sheet, though a continuous feed on a long single sheet might be employed, the sheet being divided after printing. To provide this interrupted feed, I make the cam 53 which operates the paper feed in t is form of two rings, side by side,

- independently adjustable, and I position these rings so that after the first sheet is fed,-

a depression phone of the rings operates on the arm 52 to lowerthe roller 51 and cause a subsequent feeding shortly after the first sheet has clearedthe feeding rollers- The set screws 110 (Fig. 1) illustrate means for clamping the two cam rings in adjusted position, though if desired the clamp shown in Mr. Gammeters application No. 396,571 may be em loyed.
